Response

Transactional email updated

successboolean
warningsstring[]

Non-blocking advisories about the blocks that were written. The write succeeded. Present when a field was not part of the block schema and was discarded, or when a supported field does not control what its name suggests for that block type - for example styles.backgroundColor on a button colors the band behind the button while the fill comes from buttonColor. Each message names the offending path and the fields that block does accept. Absent when there is nothing to report.
